6. Operating Instructions
- Submersion: Ensure the filter is completely underwater at all times during operation. Running the filter dry can cause irreversible damage to the motor.
- Power On: Plug the filter into a grounded electrical outlet. The filter should start immediately, drawing water through the intake and expelling filtered water through the outlet.
- Check Flow: Verify that water is flowing out of the filter's outlet. If there is no flow or weak flow, unplug the unit, check for obstructions, and ensure proper submersion before plugging it back in.
- Continuous Operation: For optimal water quality, the filter should operate continuously.

7. Maintenance
Regular maintenance is crucial for the efficient operation and longevity of your filter, as well as for maintaining healthy aquarium conditions.
- Unplug: Always unplug the filter from the power source before beginning any maintenance.
- Remove Filter: Carefully remove the filter unit from the aquarium.
- Clean Filter Sponge: Disassemble the filter casing to access the filter sponge. Rinse the sponge thoroughly with old aquarium water (from a water change) or dechlorinated tap water. Do not use untreated tap water as it can kill beneficial bacteria. Clean the sponge until most of the trapped debris is removed, but avoid excessive cleaning that might remove all beneficial bacteria.
- Clean Impeller: Periodically, remove the impeller cover and clean the impeller and its shaft. Hair, debris, or mineral buildup can impede its function.
- Reassemble: Reassemble the filter components, ensuring all parts are correctly seated.
- Reinstall: Place the filter back into the aquarium, ensuring it is fully submerged, and then plug it back in.
Frequency: Clean the filter sponge every 2-4 weeks, or more frequently if water flow significantly decreases or the aquarium appears cloudy.

8. Troubleshooting
- Filter Not Starting:
- Check if the power cord is securely plugged into a working outlet.
- Ensure the filter is fully submerged in water.
- Inspect the impeller for any obstructions or damage. Clean if necessary.
- Reduced Water Flow:
- The filter sponge may be clogged. Clean the filter sponge as described in the Maintenance section.
- Check the impeller for debris or buildup.
- Excessive Noise:
- Ensure the filter is securely mounted and not vibrating against the aquarium glass.
- Check the impeller for any foreign objects or damage. A damaged impeller can cause rattling.
- Ensure the filter is fully submerged; air in the pump can cause noise.
